"We know that Salomon could leave at any moment," Girard said. "We know the situation with Divock. Whatever happens, there will be compensation."

Origi, who helped Belgium to the World Cup quarterfinals, is due back at training with Lille on Monday.

Kalou, 28, was part of an Ivory Coast side that did not make it past the group stages of the World Cup.

The former Chelsea forward, who has scored 30 league goals in two seasons since leaving England, failed to join up with his club as planned last Monday. He is now set to link up with the team on Thursday.

If they are still at the club, both Kalou and Origi are set to sit out the first leg of Lille's Champions League qualifier against Grasshopper Zurich.

Lille's two other World Cup players, Nigeria's Vincent Enyeama and France's Rio Mavuba, will also miss Tuesday's game in Switzerland.
